Interior structural repairs in Fort Lauderdale require experience, precision, and a thorough understanding of how water, age, and load changes affect the structural elements hidden behind finished building surfaces. Cracked or bowing walls, sagging ceilings, floor settlement, and beam deflection inside commercial buildings and residences are symptoms of structural issues that only get worse when ignored. At Planet Construction FL, we diagnose interior structural damage accurately and execute repairs that restore the building's integrity — often while the building remains occupied.
Full 360° rebar undercut, mechanical rust descaling to bare metal, and cathodic zinc primer application.
Engineered multi-tier shoring towers safely support live and dead superstructure loads prior to chipping.
Turnkey threshold special inspections, concrete cylinder break tests, and final municipal certificate of completion.
Interior structural problems hide behind drywall, ceilings, and finishes — which is exactly why they're so dangerous. By the time a sagging beam, cracked slab, or rotted framing member is visible, the damage has usually been spreading for years. Cosmetic fixes paint over the symptoms while the real issue keeps eating away at the structure underneath.
We start with diagnosis — opening up just enough to find the actual cause, whether that's water intrusion, corroded rebar, failed framing, or a structural overload. Then we repair the source, rebuild the affected structural members, and restore finishes only after we know the underlying problem is solved. The result is a repair that lasts, not a cosmetic patch.
Interior structural problems announce themselves in predictable ways. Diagonal cracks running from the corners of windows and doors indicate foundation settlement or structural frame movement. Horizontal cracks in concrete block or masonry walls suggest lateral pressure or wall failure. Ceiling sags, particularly in concrete-framed multi-story buildings, may indicate slab deflection, tendon failure in post-tensioned slabs, or progressive spalling deterioration above. Floors that feel springy, slope noticeably, or have developed cracks in tile finishes can reflect slab deterioration, settlement, or framing failure beneath the finish surface. Any of these signs warrants professional structural inspection — not cosmetic patching.

Request Leak Diagnostic →Inside Fort Lauderdale's concrete-frame commercial and residential buildings, the most common interior structural repair work involves concrete spall repair on ceilings and beams — particularly in areas exposed to roof leaks, plumbing failures, or chronic moisture. Spalled or delaminated interior concrete is removed to sound substrate, rebar is treated and supplemented where needed, and the profile is restored with FDOT-approved repair mortars compatible with finish coat application. Interior beams showing deflection or cracking receive full structural assessment before any repair approach is determined — the repair must address the structural condition, not just the cosmetic appearance. Carbon fiber reinforcement is available as a beam strengthening solution where load demands require it.
Concrete structural restorations intersect with waterproofing membranes, expansion joints, and municipal milestone permits. Dividing trades creates delays, finger-pointing, and voided warranties.
Separate concrete patchers, painters, and coating contractors frequently void each other's warranties. If water intrusion recurs, the waterproofer blames the concrete mortar while the mason blames the sealant.
John Kraja directly manages the entire structural restoration under dual state licenses (CGC1517295 & CCC1329271). In-house crews chip spalls, treat rebar, cast structural mortars, and apply warranted traffic coatings under single-source accountability.
We pull permits directly across Fort Lauderdale, Pompano Beach, Hollywood, Boca Raton, and Weston building departments. We coordinate engineering special inspections daily to prevent costly stop-work delays.
Floor slab settlement in Fort Lauderdale's buildings most commonly results from subgrade soil movement — a consequence of South Florida's sandy soil conditions, water table fluctuation, and variable subsurface conditions. Settled slabs produce trip hazards, drainage problems, door and window alignment failures, and in severe cases, structural separation between the slab and building perimeter. Planet Construction FL addresses floor settlement through slab lifting (mudjacking or polyurethane foam injection), targeted slab replacement, and perimeter slab repair at wall-floor interfaces. Slab cracks that present trip hazards are ground flush or repaired with semi-rigid filler systems depending on slab movement characteristics.
Technicians review engineer reports and conduct acoustical hammer sounding surveys to map hidden subsurface delaminations.

Water damage is the most common driver of interior structural repair work in South Florida buildings. Chronic roof leaks, pipe bursts, balcony or deck waterproofing failures, and window frame leaks all deliver sustained moisture to interior structural elements — concrete beams, slab soffits, masonry walls, and steel framing. Planet Construction FL assesses the full extent of water-damaged structural elements, not just the visually obvious areas, using moisture meters and probes to map the actual extent of saturation. All structurally compromised concrete is removed and replaced. Rebar corrosion is treated. The interior is restored to a condition appropriate for finish application by others — paint, tile, drywall — completing the handoff cleanly.

In most cases, yes. Interior structural repairs in commercial buildings and occupied residential units are phased to work in specific areas while other spaces remain in use. We coordinate access, noise schedules, and containment to minimize disruption. In cases where areas must be vacated temporarily for safety or access reasons, we communicate requirements clearly in advance so property managers can plan accordingly.
It depends on the scope and nature of the damage. Isolated spall repairs on interior ceilings and beams may not require engineering. Repairs to load-bearing elements — columns, primary beams, floor slabs supporting significant loads — should involve a structural engineer to confirm the repair design. Planet Construction FL coordinates with licensed structural engineers where engineering documentation is required and can recommend experienced local firms if needed.
Location, pattern, and width are the key indicators. Cracks at door and window corners, diagonal cracks in walls, horizontal cracks in masonry, and through-cracks in concrete elements are potential structural concerns. Fine surface map cracking in plaster or stucco finishes is typically cosmetic. When in doubt, schedule a professional inspection — the cost of an assessment is minimal compared to the cost of misjudging a structural issue as cosmetic.
The most common cause is moisture infiltration from above — roof leaks, plumbing leaks, or balcony and deck waterproofing failures — that keeps the concrete slab above the ceiling perpetually saturated. Saturated concrete accelerates rebar corrosion, and as the rebar expands, it fractures and spalls the concrete on the ceiling face below. In older concrete buildings, decades of moisture exposure from normal condensation and building envelope leakage also contribute to interior ceiling spalling.
We inspect, diagnose, and recommend — at no cost. You'll know exactly what's wrong and what it takes to fix it before you commit.
